All angles must total 180°

1) x = 180° - 45° - 56°                4) a = 180° - 63° - 90°
    x = 79°                                       a = 27°

2) z = 180° - 44° - 90°                5) a = 180° - 135°
    z = 46°                                       a = 45°

3) x = 180° - 47° - 45°                6) x = 180° - 52° - 90°
    x = 88°                                       x = 38°
    y = 180° - 133°
    y = 47°
